Abstract
OBJECTIVE: The purpose of this study was to determine hepatitis B virus (HBV) screening rates in patients receiving anti-tumor necrosis factor (TNF)-α therapy and the frequency of HBV reactivation in patients with resolved hepatitis B virus infection (hepatitis B surface antigen [HBsAg] negative, hepatitis B core antibody [Anti-HBc] positive). PATIENTS AND METHODS: Data from 1834 patients who underwent anti-TNF-α therapy in the Rheumatology, Gastroenterology and Dermatology Departments of our hospital between 2010 and 2020 were retrospectively analyzed. Within 6 months before the initial anti-TNF-α therapy, performing a HBsAg and/or anti-HBc test is defined as HBV screening. HBV reactivation is defined as the presence of detectable serum HBV DNA or HBsAg seroconversion from negative to positive. RESULTS: The overall HBV screening rate was 82.3% before starting anti-TNF-α therapy. There was an increasing trend in HBV screening rates during the years analyzed (64% in 2010, 87.4% in 2019) (P < .001). Before anti-TNF-α therapy was initiated, 272 patients were HBsAg negative and anti-HBc positive. Among these patients, HBV reactivation did not occur in 31 patients who received antiviral prophylaxis, whereas HBV reactivation occurred in only 1 (0.4%) of the 241 patients who did not receive antiviral prophylaxis. CONCLUSION: Hepatitis B virus screening rates prior to starting anti-TNF-α therapy were relatively high, and its trend was increased by year. HBV reactivation because of anti-TNF-α use rarely occurred in patients with resolved HBV infection. Further studies are needed on whether routine anti-HBc screening and/or HBV DNA follow-up are necessary in these patients aside from HBsAg.
